The jig. tank compartments A and plungers B are arranged on oppositesides of the sieves C and O and serve to produce intermittent 'upwardcurrents ofwater through'the, sieves, as will be readily under.-

former passing over shield'E to while the latter'settles upon sieve. Cfrom which it is held from discharging may be removed by means of anelevator operating therein. By placing more. or fewer stops on chain F,or by increasing or decreasing the speed of the chain, the frequency-ofthedischarge may be regulated as desired. g As seen in Figs. 1 and 2,the short shafts which carry the sprocket wheels at the up- 91 ends ofchains F and F, are connected y an -=intei-mediate sprocket chain Fwhereby 'saidshafts and their sprocket w 1s, and consequently the chainsF and F ,zare-causeddo maintain a definite. rate or ratlo of speed.Chain F receives its mo- -t 0n through suitable gearing, from a drivenshaft F3.

Thus it will-1 be seen that both chains Fand F. receive power and motiona common source, and that, in any "convenient way, as for instance, byvarying the number or spacing of thestops on either chainor on thetwof'chains, any desired "ratiom'ay be established between theopenddiSchaI'gQ-Q. valves-for sieves C and G; E and 13'. over;flowshields from sieves C and C and F ing and closing of the valves Dand D. In

:thls'Way I am enabled to control accurately the amount of materialdelivered from the tail of each'sieve, and the amount over the overflowshields E and E. As the (valves are opened only at intervals, it thuscarried becomes possible to maintain on each sieve any desired depth ofthe lower stratumor layer of material, and thus to effect in the onemachine, and by the two sieves, a separation of the material into threedifierent classes, to wit, the slate, the bone, and

purepoal, in the case. of coal, and correspondmg products 1n the case.of ores and other minerals.

The coal and bone passing to sieve O are i there separated one from theother, the bone settling upon the sieve and" the pure coal passing oninto compartment H, whence it may be removed by means of an elevator.

' elevator.

The valve D' 'isoperated by chain F? in The water in tank I is returned.to the plungers B, by means of-pump J, and pipes h, and thus may beused over and over again.

By this construct-ion, it will be seen that the material is separatedinto three distinct parts, namely, slate, bone and coal, and thus apurecoal obtained.

In the foregoing ferred to detachable stop-carrying links as descriptionI have reaffording means for adjusting the stops,v or varying the numberand relation of stops in the two chains, and this is the preferred modeof effecting such adjustmentior variation. As these chains are oftheordinary separable link variety, it is obviously prac-' ticable toemploy a greater-or a lesser number of stop-carrying llnks, and thus todecrease or increase at will the distance be ings; but

While I have shown and described the preferred means for carryingmy'invention' into eflect,'this is capable of variationwithout'departing from the spirit of the invention. I therefore do notwish to be'lim ited to the exact construction shown in the draw- What Iclaim as new by Letters Patent is:
